Chemical Equilibrium

Question 1

what is a reaction’s equilibrium?

Answer 1

rate of forward reaction = rate of reverse reaction. e.g. rate of evaporation = rate of condensation. there is no net gain/loss but the system is still dynamic

Question 2

what do you disregard when trying to find K?

Answer 2

solids and liquids. they’ll be 1 instead

Question 3

what to do if reaction quotient is greater than 0? less than 0?

Answer 3

if greater, that means too many products so shift left. if less means too little products for shift right

Question 4

what is le chateliers principle?

Answer 4

shift to reestablish disturbed equilibrium. changes in temperature, pressure, concentration, etc.

Question 5

what to note about temperature change w le chateliers principle?

Answer 5

is it endothermic or exothermic? when added to products it is exothermic and will shift to left. when added to reactants will shift to right and is endothermic

Question 6

how to change partial pressure in a system?

Answer 6

can change volume. will cause equilibrium to shift left or right
